To (ir/ZZ 1,071,011@ it may con/cern:

Be it known that I, GEORGE GRAHAM, a citizen of the United States,residing at Dorchester, in the county of Wise and State of Virginia,have invented certain new and useful Improvements in Oil-Flasks, ofwhich the following is a full, clear, and exact specification.

This invention relates to miners oil-flasks.

In mining' operations it is well known that the miners have attached totheir caps a small lamp to give them light in carrying on their work andthat said lamps must from time to time during the day or during a shiftbe refilled as the oil is consumed.

The object of this invention is an oil-flask to be carried in the minerspocket from which to refill his lamp when necessary; and to this end theinvention consists, broadly, in a ask or receptacle normally closed by avalve which prevents escape of oil. the flask and its valve being soarranged that it may be readily withdrawn from the pocket andmanipulated to fill a lamp by the use of one hand, the other hand beingfree to hold the lamp.

In the accompanying drawings, in which similar letters of reference areused to indicate corresponding parts in each of the several views,Figure l is a perspective view of a miners oil-fiask embodying myinvention. Fig. 2 is a top plan view thereof, the valve being shown in aposition to close the flask. Fig. 3 is a section on Ithe line 3 3 ofFig. Q, and Fig. 4f is a top plan View of Fig. 3 with the valve removed.

The flask A is preferably made of metal and of oval or attened shape tolie flat against the person and may be stamped from sheet or cast, aseconomy and convenience may dictate.

The flask at its upper end is made small to be encircled by the hand andterminates in a plug A somewhat thicker than the body of the flask for apurpose to be hereinafter explained. This plug A may be formed integralwith the `body of the iiask or be secured immovably thereto by animpervious joint a, formed by spinning' the neck of the body upon theperiphery of the plug or by solder. The plug is provided atdiametrically opposite points adjacent to and preferably equidistantfrom the periphery with apertures a and a2 to provide for the freepouring of oil from the one, while air may enter through the other tofacilitate the flow ofoil. The plug is further provided at a suitablepoint with a large opening a3 to be used in filling the flask andcentrally with a tapped hole a4. i

Above the top of the flask-mouth and plug A is secured a disk valve Bcircular in contour and having a depending flange I); which fits snuglyupon the iiask-mouth, as shown in Fig. 3. This disk Valve is secured tothe ask by means of a screw or bolt O passing centrally through thevalve and engaging the female threads of the central tapped hole a," ofthe plug. The valve B is provided at diametrically opposite pointscorresponding to the apertures a' and a2 of the plug with apertures .b'and b2, the first, b, corresponding in diameter to that of thefilling-opening a3 of the plug A and the latter corresp'onding indiameter with that of the apertures a' and a2 of the plug.

Secured within the ianged disk valve B is a packing or washer D, ofrubber, leather, or other suitable material, having openings d and @Z2arranged opposite and corresponding in diameter respectively with theopenings and b2 of the valve.

Projecting from the perimeter of the valve B are lugs b3 and 5*, thelower ends of which are adapted for contactv with stops E and E',secured to the fiask-mouth in such position as to arrest the movement ofthe valve to close or'seal the flask or to permit of a ficw of oilthrough one or the other of the apertures a' and a2, air meanwhileentering through the other aperture to facilitate the iiow of the oil.

The stop E is carried by one end of a spring-latch e, pivoted in suchposition with relation to the fiask-mouth and lug b3 and the valve thatthe lower end of the latch may be moved aside, (toward the lug bi) thusthrowing stop E out of the path of the lug b3, whereby the valve-diskmay be turned further to cause the opening b of the valve to registerwith the filling-opening (fof the plug.

From the construction described it will be seen that the flask may befilled by a rapid flow of oil through the large openings b of the valveand a3 of the fplug. The valve now being shifted to bring its lugs b3and b* between the stops E and E', thespring-latch e is thrown down toraise the stop E into the path of lug 3, the latch locking in thisposition into a keeper a5, thus assuring the registry of the openings band 2 of the valve and d Z2 of the gasket D with the aperturesa' and co2of the plug A to admit the How of oil from and entrance of air into thelask or to close said apertures, thus sealing the flask.

It will be noted that the iask here described may be quickly lledWithout removal of or danger of loss of a stopper or screw-plug and thatall manipulations of the valve to fill a lamp are accomplished by thethumb or linger of one hand of the user resting between the lugs of theValve, whereby the flow of oil may 'be instantly shut of in the'event ofmine emergencies and other necessities.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent ot' the United States, 'isl. A flaskcomprising a body having a plug provided with apertures, and having afixed and movable stop, a valve-disk journaled on said plug and havingopenings adapted to reg- GEORGE GRAHAM.
